To all whom it may concern:

Be it known that I, WiLLIAM HERBERT LOWE, a subject of the King of Great Britain, residing at 35 Mowbray road, Brcndesbury, in the county of Middlesex, England, have invented certain new. and useful Improvements in Electrolytes, of which the following is a specification.

This invention relates to improvements in electrolytes to be used in closed batteries,

' such as are described in U. S. Patent $0.

940,734; of November 23, 1909.

In the specification of the British Patent No. 26649 of 1909, a process of making an electrolyte, which is similar to the electrolyte claimed in the United States Patent referred to above, is claimed. This process consists of first rendering bichromate of soda anhydrous, and then mixing it with concentrated sulfuric acid toform a hard mass. In this specification it is stated that preferablyBZ ounces of anhydrous bichromate of soda are mixed with 18 fluid ounces of concentrated sulfuric acid.

Specification of Letters latent.

Patented Nov. 5, 1912.

Application filed May 10; 1912. sell-m1 No. 696,484.

I have discovered that an improved electrolyte .is obtained by adding 28 ounces of anhydrous bichromate of soda in place of 3:2-

bunces to the same quantity of sulfuric acid.

Such an electrolyte is more efiicient for use in the battery and withstands better any change of temperature. The hard mass formed may be ground to a powder and mixed with salt and water. I have also found that a better result is obtained if 5 ounces of salt are used in place of 4: as is stated in the above mentioned specification.
